I don't know why, but the "Double Facepalm." magnet makes me smile every time I see it. Isn't it great how we, as fans, can pick out minutia from the films and television shows we love and escalate them to universal cultural status?
In Previews these magnets were listed as "Please Inquire" so heaven only knows how much they cost. Remember the $60 Star Trek sticker set? (You can check it out here.)
